PROCESS FOR MAKING NON-ALCOHOLIC BEVERAGES FROM FERMENTED'LIQUIDSE'V To all whom et may` concern: d

`Be it known' that We, HERMANN LINZFJL' and CARL BIsonoFF, subjectspfthe King of Prussia, residing yin Berlin, Gerfrany, have invented an Improved Process for Making. Non-Alcoholic Beverages from` Fermentd Liquids, of Which the following is .a specification. i

In the recesses hithertolused for extractlng the a cohol frombeer for the purpose of making `a non-alcoholic beer-like beverage or drink, the beer is subjected to'distillation,

, returned to the beer.

` either at ordinary pressure or in avacuum, a

redux-cooler being used'in order that all volatile products other thanthe alcohol may be During the distillation, when the process is carried on in a vacuum, it has been customary to pass a current ci' inert gas through the beer to produce a continuous agitation therein. These old processes-iiolve certain disadvantages however. s a more or less considerable concentration of the beer always results during the distillation and precipitates also occur, which cannot 4be subseqpently dissolved. Furthermore, even after -stilling off about one-third of the entire liquid, a certain proortion of alcohol is stil eer, while if'by the use of the reflux cooler, the volatile substances in the beer which are carried oil with the alcohol in the distillation,

' urn, its norma are returned to the beer in the evaporator, the lengthfof time during which the process must be continued to secure approximate deal'coholization very seriously impairs thev quality of the final product. We have found that when de-alcoholizing a fermented liquid, for instance beer, in vacuconstituents, except the alcohol which is intentionally removed, are best preserved -by keeping vits volume uniform during' the distillation.. To this end We inject into the beer or other liquid during the Ydistillationfa continuous current of steamv and Iair, or the likeinert gas. IThe addition of air to the injection has been found 'teaccelere-te the. evaporation of the alcohol so.

that it takes placezmu'ch more rapidly than c, When'steam alone is injected, While on the other-hand, the condensation of the steam- While assing through the beer'replaces the.

be Ldetermined only bytests.y ItWill'natu-' rally vary Wit the quantity of alcohol contained in the b er or other'liquid xvhichis to 4 be de-alcohofliz'e It hasbeen ioundthat 6 or 7 liters of wat r in the form of steam'are su'flicientior the treatment of 1,00 'liters ofl lthejusiual Munich beer. The amount'\of air introducedfis regulated by the strength of the ste`am'cu1re`1t\which sucks the air'with it into the evaporator.

It is only by experi'f mental tests'that the proportion can' befdetermined for the treatment vnthe' particular c liquid in hand. rPhe currentof airand steam suc ed or drawn oli' by the exhaust carries the alcohol Withit, Whilethe lesseasily volatile ingredients of the hops and of the aromatic products of the beer remainin theliquid,'and, byl reason of the fact/that the co centration of the de-alcoholized liquid re-' Inains the same, practically no precipitates are formed.

A test of'the process maybe ,readily made with say 10 to 12 liters of beer of about 2.' to 4- per cent. by Weigh't'oi alcohol in a vacuum apparatus of a capacity of about 30 liters.

Distillation for about an hour :at a temperayture of from 40 to 50 C; (under from 50- 60 mm. pressure) will give a de-alcoholized beer in which there remains but about 0.75

' A suitableapparatus for carrying out this process is shown in the accompanying drawlng.

An evaporator A with manometer, etc. is

shown connected through the pipe Owith a steam boiler B provided withl a gage G.

Steam is introduced into this boilerB through a pipe P to heat the Water therein. The de-v crease of the amount of the Water in the boiler as shown by the gage indicates-the quantity of water avhich is being introduced into the beer in the form of steam. Near the entrance ofthe pipe O into the evaporator is located an'air intake controlled 'by-the valve C provided with a nozzle or relief valve. As the steampasses through the pipe intrnthe evaporator A, air is sucked through the valve C and mingles with the steam as 1t enters the evaporator. or other liquid in the evaporator the 'steam and air and the alcohol .taken up thereby,

After passing through the beer` pass through the pipe S into a cooler D, f

through which the pipe S is passed` in the form ofa coil. From the cooler the. ipe S: leads the condensed Water and alcoho to an .overliow vessel E which is provided vv'itha to the collecting vessel T. An alcohol areter is precisely the same.

,tank L,' anl finally it is ometer F is connected -to the latter in like manner as the gaffe G to thel boiler B. This "apparatus isf simi ar to that lcommonly used in rectifiers for 'benzole and the likev except that in the present oase it Works under vacuum which is obtained throughthe exhaust. pipe K opening into the collecting chamber T.4 The rise and .fall ofthe alcohol varch/nderIhe contents of this' collecting vessel may be drawn off through the cock V. The beer after hav/i'xig/ been dealcoholized, is forced, by m an's of carbonio yacid compressed ,in the tank H which-is connected through a/valved pipe W with the evaporator A, through the pipe N, which passes coiled t/hroilgh the-cooler D to a filter J1. From .here it is led to the impregnator K coruaetedV with theearbonic acid led lto the bottling machiie M.
